Great  Time owned: 6 to 12 months
Very happy with it. Works good on all three bands. the 1.26m band is a little higher on SWR than the others, but that was to be expected. Overall, great value.

Works very well  Time owned: more than 12 months
I currently own two Comet CX-333 Triband antennas. Based on my experience, the quality and performance of the CX-333 has always met my expectations. Historically, I purchased my first Comet CX-333 in the late 90's as a base antenna. It was used for several years, but then stored away after a move to a new location.

Last year, I became interested in experimenting with APRS on the 2 meter band. Therefore, I decided to mount the old CX-333 on my roof using an unused Dish antenna mount. The bottom of the antenna is about 24 feet from the ground. Using a Yaesu FT-5100 at 5 watts, APRS.FI reports that my APRS signal is being gated into the APRS system by several stations. One station is over 50 miles away.

Until recently, I have not been active on VHF and UHF phone for many years. I decided to add that capability to my station. Based on past favorable experience. I purchased a second Comet CX-333 a few weeks ago. That antenna was installed at the top of a tower. The bottom of the antenna sits at 86 feet, and is being fed with 175 feet of Davis Bury Flex 400 cable. On the bands of 2m/1.25cm/70cm, I am hearing more than 40 different repeaters from my semi-rural location. Some of the repeaters heard on 2 meters are over 125 miles away. Local repeaters are easily accessed, and reception of repeaters within a 30 mile radius are 60 over S9. Local contacts a few miles away on simplex are also easily maintained with minimal power. A mobile station that was 20 miles away, reported that I was 60 over S9 when I was using 50 watts on 2 meters.

In my opinion, the Comet CX-333 is a great antenna. It provides a good match for the designated bands of design, and has proven to have adequate performance at a reasonable cost.

Can Not Couple  Time owned: 0 to 3 months
Just opened my new antenna, looked over the instructions. Simple enough. I can't ever get past step one to couple the top and bottom sections. The top section has the male connection so far up the sleeve there is no way to make the connection. Anyone else have this problem?

2 years later, still plugging along!  Time owned: more than 12 months
Two years after getting this antenna up, it's still plugging along. I picked up a SO-239 to male SMA pigtail and I now can listen all over the place!

Needless to say, I have a ton of freqs in my handheld and I listen to quite a bit. I also pick up a good deal of birdies and other offending transmitter issues around here too.

All in All, it was worth the money, I still haven't gotten a dual band mobile and a 220 MHZ mobile with a triplexer and duplexer. Someday I will, hopefully.

Pick one up, you can't go wrong.

5+ years of solid performance  Time owned: more than 12 months
This is an update from my review in January of 2009. As of last night, the VSWR performance of this antenna is still within a few percent of when I installed it 5 and a half years ago. My analyzer will only let me check resonance up to 180MHz, but it was still close to the same resonance points as 2009. I was only able to check the 222MHz and 440MHZ bands with a VSWR meter. What maintenance have I done? Other than going up on the roof and lowering the mast to visually inspect the antenna twice a year, none!

5 Years and Counting  Time owned: more than 12 months
My CX-333 was easily assembled and readily mounted upon a tripod with ten foot mast on my roof at 45 feet AGL. It performs as expected on all three bands fed through a Comet CFX-324 triplexer. It has endured several severe storms with nary a wimper. Hard to go wrong with this one.

Rugged & Holds Up Great !  Time owned: more than 12 months
I've had my vertical up over a year. It has withstood 70 MPH winds last winter in a blizzard we had not to mention strong gusty winds this summer during violent thunder storms. It is 50 feet up in the air at the base.

It has a decent SWR on all 3 bands while it takes a licking and keeps on ticking. I highly recommend it!

Works good but very poorly designed   Time owned: more than 12 months
Works ok but very cheap metal and probably would not last long mounted above 50 feet. Metal very thin and bolt holding mast to base will shear out in a couple of month

Great Antenna  Time owned: 3 to 6 months
I also have the CH-333 tribander. Extremely easy to put together ( like 20 minutes). Light weight attached to a roof vent pipe. I get into repeaters 155 miles away no problem in the early evenings. SWR pretty flat. Packed well in a thick, heavy tube by HRO. It fun to tune around the VHF / UHF bands and look for far away repeaters to jump into.

Great antenna   Time owned: 0 to 3 months
Great antenna just replaced a Diamond X50 that I had on both VHF and UHF repeater with the CX333 night and day difference, very happy with it.
